COLLAPSIBLE GREASE-CAPSULE.

Specification-of Letters Patent.

Application filed September 10, 1915. Serial No. 49,933.

.To all whom it may concern:

Be it known that I, LLOYD G. COPEMAN, a .citizen, of the United States, residing at Flint, county of Genesee, State of Michigan, have inventeda certain-new and use'-" the conventional form of grease-cup by fill ting it on the hands.

ing the same with hard grease with the aid of a knife or other tool. It has been founda rather disagreeable job to fill a grease-cup in thisway as it requires not only time but itis difficult to put the grease in the cup Without some of it being left on the sides and without distributing the grease in places where it is undesirable and sometimes get- I do away with these inconveniences and difiicult-ies by employing a paper grease-capsule in which the hard grease may be packed and sold. These capsules may be placed in the conventional grease-cup that are so designed that they will collapse without in any way interfering with the discharge of the grease. This will more fully appear in the description following.

In the drawings, Figure 1 is a view of the open end of the capsule. Fig. 2 is a longitudinal section of the capsule. Fig. 3 is a view of the disassembled grease-cup and capsule, largely in section. Fig. 4 is a view of the same parts assembled partly in section. Fig. 5- is a similar view showing the follower of the grease-cup advanced and the grease-capsule collapsed. I

a designates the cylinder of a conventional grease-cup which is provided with a screw-threaded nozzle 6 through which the grease is forced and which may be screwed into one of the parts to be lubricated. The opposite end of the cylinder is threaded at 0 to receive the screw-threaded cap (1 into which runs the threaded screw 6 which is provided with a follower f.

The capsule is designated 9 and comprises a cylindrical shell. of paper closed at one end and open at the other. This capsule is so constructed that when subjected to pressure on its closed end it will collapse in the manner shown in Fig. 5, that is to say, in a large number of bellows-like folds. It is very material that the grease-capsule collapse with a large number of bellows-like folds or otherwise it might collapse in such a way as to have the folds practically trap the grease in the cup so that it would not be forced through the passage-way in the nozzle.

From the above description it will be seen that the grease can be packed in the greasecapsules and sold to the trade in this shape, and the user may then merely insert the capsule in the grease-cup by removing the ing a bottom portion provided with a.rela

tively small discharge opening, of a collapsible capsule located within the greasecup, a part of the bottom portion of the grease-cup being formed and arranged to furnish a perpendicular abutment for the end of the collapsible capsule, the said capsule having a relatively large open inner end of substantially greater area than the discharge opening of the grease-cup so as to span said opening and bear against the perpendicular abutment at a point remotely related to the discharge opening of the grease-cup, and means for collapsing the capsule upon the abutment, substantially as described.

In testimony whereof, I sign this specification.

LLOYD G. COPEMAN.
